Friend problem!?!?!

Okay so some of my “closest friends” have just been full fledged bitches to me and I’m not sure what I’ve done to make them so judgmental to me, I have a large butt and thighs with a Petite waist and I’m short so it’s really hard for me to find pants that fit right however my “friends” keep telling me I need to buy bigger pants and my pants need to be not so tight and every time I try to explain they tell I’m just coming up with excuses and sometimes they will talk about how I dress like a whore and if I wear makeup she ask me why I’m asking for attention stuff like that, but a lot of the times it’s to my face and im not sure if it’s a jealousy thing or what I should do?? (Excuse the grammar)
